Exam-style question
Try this first
Explain why a nucleus with a neutron-proton ratio less than 1 is likely to undergo alpha decay.
Model answer
What a good answer should say
- A nucleus with a neutron-proton ratio less than 1 tends to be unstable and will likely emit an alpha particle to reduce its mass and increase stability.
Explanation
Why this works
This answer is strong as it connects the neutron-proton ratio to the stability of the nucleus and the resulting decay mode. It tests the student's ability to apply knowledge of nuclear instability to predict decay behavior.
